SAMUEL F. HILL AND JOHN W. COGHRAN, OF INDIANAPOLIS, INDIANA.

Application filed January 20, 1921.

To all whom it may concern:

Be it known that we, SAMUEL F. HILL and JOHN W. CooHRAN, citizens of theUnited States, residing at Indianapolis, in the county of Marion andState of Indiana, have invented certain new and useful Improvements inVentilating-Sash Fasteners, of which the following is a specification.

This invention relates to sash fasteners and is so constructed that whenattached to window frames, said frames may be opened a limited distancefor ventilating purposes and may not be opened a sufiicient distance toadmit the passage of a body below or above the frames.

A feature of the invention is the provision of a plate having aplurality of substantially key socket openings therethrough, whichopenings project over the glass portion of the window structure andbeyond the edge of the sash to which the plate is attached so that itwill not be necessary to deface the window frame or sash in applying theplate to use.

A further feature of the invention is the provision of a pin or bolt,and a housing therefor, which is designed to be attached to the othersash of the window structure, the end of the pin being shaped to fit thesockets or openings in the plate attached to the other sash, the boltbeing spring pressed.

A further feature of the invention is in so arranging the spring inconnection with the bolt that it may be utilized to direct tensionagainst the bolt in either direction.

A further feature of the invention is the provision of openings in thehousing for the bolt similar to the openings in the plate, whereby theend of the bolt may be withdrawn entirely into the housing and the boltgiven a partial rotation, thereby holding the end of the bolt out of thepath of the upper sash of the window structure, thus obviating anypossibility of marring the sash when said sash is moved to its full openposition.

Other objects and advantages will be hereinafter more fully set forthand pointed out in the accompanying specification.

In the accompanying drawings, which are made a part of this application,

sash, and 3 the lower sash, said sashes being vertlcally slidable in theframe. In order to provide ventilating space either above or below thesash and at the same time secure the sash so that they cannot be openedfurther than the ventilating space, a plate 4. has one of its edgesattached to the vertical side rail of the upper sash 2 while theopposlte edge thereof projects a distance beyond the inner edge of therail of the sash and extends over the glass or visual space n the sash,and in this projecting portion is provlded a plurality of spaced sockets5 which are preferably shaped similar to a key socket, one end of thesocket being preferably circular and the opposite end thereof oblong.Cooperating with the sockets 5 is a securing bolt 6 which extendsthrough a housing 7 which housing is preferably fixed to the top rail ofthe lower sash 3 and is so positioned that the inner end of the bolt 6will enter the sockets 5 in theplate 4. The inner end of the bolt 6 isprovided with a laterally extendinglug 8 'which, when the bolt is beingentered into or removed from one of the sockets, enters the elongatedportion of the socket while the body, of the bolt enters the circularportion of the socket and it will be readily seen that when the end ofthe bolt has been extended through one of the sockets and the bolt givena partial rotation, the lug 8 will overlap the inner face of the plate 4and securely fasten the two sashes together until such time as the boltis rotated to again bring the lug 8 into registration with the elongatedportion of the socket. The two walls of the housing 7 through which thebolt extends are provided with sockets 9 similar in outline to thesockets 5, so that the bolt can be readily entered through the housingand the inner end of the bolt 5 may be held entirely out of the path ofthe upper bar of the sash 2 by withdrawing the end of the bolt 6entirely into the housing 7 and then rotating the bolt to move the lugout of registration with the elongated portion of the socket 9 in theinner wall of the housing 7, this action holding the bolt in inoperativeposition until such time as the lug is again plate& when either devicell) may be. very.

brought into registration with the elongated portion of the socket 9. p

The lengthwise movement of the bolt 6 in one direction is determined bya coiled spring 10 which surrounds that portion of the bolt 6 within thehousing 7 and if inward pressure is to be directed against the bolt soas to normally. hold the bolt extended into the path of the plate 4:, apin 11 is extended transversely through the bolt 6 forwardly of thespring 10, washers 12 and 13 being preferably positioned at oppositeends of the spring, the washer 12 bearing' against the pin 11, while thewasher 13 bears against the outer wall of the-housing' 7. If it isdesired, however, to exert the pressure of the spring 10 against thebolt 6 in the opposite direction, or outwardly, the'pin 11 is removedfrom the opening 1 through the bolt 6 and entered through a similaropening 15 also extending through the bolt 6, the spring 10 beingcompressed between the washers 12 and 13. In this instance the washer 12will bear against theinner face of*the wall of the housing 7 .while thewasher 13 will bear against the pin-when it is-introduced into theopening 15, and when so arranged the bolt 6 will be moved outwardly bythepressure of the spring when the lug on the bolt is brought intoregistration with the elongated portion ofthe socket 5 through which thebolt extends. V

When the spring 10 is arranged as shown in Fig. 3 of the drawings, thebolt 6 is manually moved: outwardly until the inner end thereof isentirely disengaged from the the upper or lower sash may be properlyadjusted for ventilating purposes, and the bolt then released,whereuponthetension of the spring 10 will force the bolt inwardlythrough the registering socket in the plate 4:, and when so entered thebolt may be partially rotated, thereby securely fastening the two sashestogether and rendering it absolutely impossible for any one to maniulatethe lock except those on the interior of the room. When the spring 10 isarranged as shown in Fig. at .ofthe drawings, it will require thatpressure be applied to force the bolt inwardly for; entering theendthereof through one of the sockets in the, plate 4:, the fasteningoperation between the-parts being the same in both instances. In thelatter construction it is but necessary tomove the lug'into registrationwith the elongated portion of the socket 5 in order to release the boltfrom the plate as the pressure of-the spring on the bolt is outwardandwill immediately move the bolt to inoperative position.

It ,will li'kewise-beseen-that in view of the simplicity of the variousparts of this cheaply constructed without lessening .the strength andduradation of the end of the hold the end bility thereof, and may bevery quickly applied to use by any one.

It will likewise be seen receiving sockets are clear of the parts of thesash to which the plate is secured it is not necessary to deface or inany manner form cavities in the sash for the accommofastening bolt, andneither will the sash show defacement to any material extent should itbe necessary to remove the fastening mechanism.

Having thus fully described our said invention, what we claim as new anddesire to secure by Letters Patent, is:

1. The combination with the upper and lower sashes of a windowstructure, of aplate secured to one of said sashes andhaving socketstherein at a point beyond the edge of the sash, one end portion of saidsocket being round and the other end portion elongated, a housingsecured torthe other sashhaving sockets'shaped similar to the sockets inthe plate, a bolt adapted to fit the round portion of said sockets, anda laterally-extending lug at the free end of said bolt adapted to fitthe elongated portion of thesockets, the lug being adapted to enterwithin said housing and of the bolt out of the path of the upper sashwhen the lug is turned out :of registration with the'socket in thehousing and adapted to pass through the sockets of said plate forsecuring the two sashes, against movement independent of each other.

2. The combination with the upper and lower sashes of a windowstructure, of a plate having one of its edges connected with one of saidsashes and its opposite edge projecting beyond, the edge of the sash,the projecting portion of said plate having a plurality of substantiallykey-shaped sockets therethrough, a housing fixed to parts of the othersash, the front and rear walls of said housing having registeringkey-shaped sockets therethrough, a bolt e'xtendin through said socketsin the housing and adapted to enter the sockets in said plate, and. alug extending laterally from one end of said bolt for fastening saidbolt against casual removal from the sockets, said bolt and lugconforming to the outlines of the sockets in the plate and housing.

3. A fastening mechanism for the upper and lower sashes of a windowstructure comprising a plate adapted to be secured to the upper sash andhaving one of its edges projecting beyond the edges of the upper sash,said projecting" edge having a plurality of vertically extended socketstherethrough, the lower portionsof which are circular and theupperportions elongated, a housing fixed to the lower sash, a pinextending transversely through the housing, a laterally projecting lugon the inner end of said bolt adapted to pass through said sockets inthe plate and that as the bolt hold the bolt against longitudinalmovement when the lug is moved out of registration with the socket, saidbolt and lug being shaped to fit the circular and elongated portionsrespectively of said sockets, and a spring within the housing adapted tocontrol the movement of said bolt in one direction.

4. A fastening means for the upper and lower sashes of a windowstructure comprising a plate having sockets therethrough, a housing, abolt extending through said housing and having a pair of spaced openingstherethrough, a pair of washers on said bolt, a spring within thehousing and surrounding said bolt between said washers, and a pinadapted to be entered in one of said openings in the bolt for directingthe pressure of the spring against said bolt in one direction, and beentered in the other open ing for directing the pressure of the springagainst the bolt in the opposite direction, said pin passing exteriorlyof the Washers in each instance.
